Identify your CB750P (1978)

Record the complete frame/VIN and engine markings, then compare the model year and original market with the motorcycle’s identification plate and records. A registration year, paint colour or collection photo alone does not verify the model.

Keep identifier photographs with the parts request, including any component markings. This is especially useful when the registration year and the motorcycle’s original-market model designation differ.

For help locating identifiers, see our Honda CB model identification guide.

Compare the cover joint and lever-end hardware

The linked alternator-cover gasket 12-5038 replaces 11397-300-306 and is catalogued for 1969–78 CB750 models. Compare its cover joint with the installed engine. The 08-0067 cable adjuster is the 8 × 23mm lever-end part; match it to the fitted lever perch rather than using the motorcycle’s year alone.

Fitment questions

Will the listed motorcycle cover clear Police equipment? Its listing gives a maximum length of 2,400mm, but no width or height allowance for a screen, panniers or other equipment. Measure the fully equipped motorcycle and confirm those clearances before choosing the cover.

How much weather protection does the selected cover claim? The listing describes polyurethane-coated fabric as water-resistant, sun-protective and mildew-resistant. It does not specify a waterproof rating or sealed seams. For prolonged outdoor storage, confirm those details rather than treating “water-resistant” as a guarantee against rain getting through.
